Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629140, here are decompositions:
- 17 + 8629123 = 8629140
- 31 + 8629109 = 8629140
- 53 + 8629087 = 8629140
- 61 + 8629079 = 8629140
- 67 + 8629073 = 8629140
- 131 + 8629009 = 8629140
- 137 + 8629003 = 8629140
- 167 + 8628973 = 8629140
Showing the first eight; more decompositions exist.
